Sacramento, California - The California Department of Justice issued an advisory reminding gun retailers that bump stocks, also known as "multiburst trigger activators" because they accelerate the rapid-fire capacity of a firearm, are illegal in California. Bump stocks reportedly were used in the Las Vegas shooting on October 1, the deadliest mass shooting in modern American history.

The advisory, issued to 2,300 dealers across California, references California Penal Code 16930, which defines bump stocks, and Penal Code 32900 and 32990, which make them illegal. Any person in the State who possesses, manufactures, imports into the state, offers for sale, or who gives or lends one of the devices has committed a crime. Penalties for violating the law can include up to three years imprisonment.
